Our Weil McLein steam boiler stopped working. We called PSE&G, who we had a worry free guarantee with, who came out and told us it had a crack and needed to be replaced. We called around and had about 6 heating companies come out to give us a quote on the job. Most came in, looked at the BSU, if even, then shot us a price and were in and out within 5-15 minutes. Everett from Building Science returned our call and when he heard that we had no heat at all and on a Friday night, arranged for the senior project manager Steve to come out to our home. Despite being out all day, the fact that he was squeezing us in and that it was later in the evening, Steve sat down with us for almost an hour. He took measurements, he checked specs, he drew us pictures of how and why things weren't working, how they should be working and why the cost is what it is and discussed payments and financing with us. Their satisfaction guarantees were very fair and were above and beyond what anyone else had offered to us. He fit us in first thing that Monday morning. The crew came out on time, explained what they would be doing, they were professional, put down tarps and coverings to keep our flooring clear, got the old boiler out, go the new one in, swept the floors after and were done 2 hours before their estimated finishing time. I cannot express enough how impressed I am with their professionalism and their quality work. They were worth every penny. read more

First and foremost we originally had our oil to gas conversion scheduled with another company. It fell though because our town requires heat loss calculations which the other company was unable to provide. After searching the internet for best Hvac companies building sciences came up. Our whole experience has been great. Rashid the owner is easily accessible for all questions and concerns. Abigail the office manager is awesome, patient and kind. We spoke very frequently and she never had a bad attitude or feeling of being annoyed. The two contractors George and Ontario were awesome. They know there job very well. We went from oil to gas with an ac coil added in two days. They were very punctual. Building sciences is the way to go if you plan on doing this job...... FLC OF West Orange NJ read more

We converted from oil to gas. Plus we got a tankless water heater installed and also replaced the central AC. Building Sciences were professional all the way - from the time Mark came out to the final insulation crew left. They even posted an on-line project management case, showing all the steps involved for me to keep track of all the things they were going to do. We shopped around for 5 different quotes before selecting Building Sciences - (who were not the cheapest but were near the middle). We qualified for the NJ Clean Energy program, and got 0% financing, all the work done, and our attic got insulted. We got an Amana furnace and AC, and a Navien tankless water heater. We are so happy with the work. Highly recommended for furnace, AC and water heater replacement. read more

We called Building Sciences to air seal and insulate our attic, as our 1950's home had always been a bit drafty upstairs and we wanted to find a way to lower our energy bills. We were able to replace our old furnace and air conditioner with new, high-efficieny models and get insulation in our attic and in the floor over our garage. We were also able to get a large rebate from the state that paid for almost half of the job! The work on our home took 2 days. When the crew arrived they were knowledgable and did a wonderful job explaining exactly what they were doing and why in regards to the insulation. Our home is noticeably more comfortable, and we would definitely recommend Building Sciences to others read more

I was looking for an affordable company. There was many bids and I wasn't happy. I stopped looking for a while. I was recommended Building Sciences by an old friend. Was skeptical but by the end of it I was happy I decided to contacted them on their website. They got back to me quick and set a meeting at my house. After looking at all the figures and the options they gave me, I made my choice. The process was simple and pretty straightforward. This company worked with my budget and helped me get 0% financing. I finally got to replace my old junky boiler and put in a furnace and a new rheem 50 gallon water heater. I had a nice experience from beginning to end. They get the job done. read more

Building Sciences provided an excellent service and presented various options we could have in the beginning. We never felt stressed during the price and service comparison process. As we are replacing a brand new heating, ventilation and air conditioning system to our home, we'd probably asked more than hundreds of questions. Yet, the owner Rashid and staff were all courteous, personal and provided us with lots of useful information. Between so many different cooling and heating company, this company offers the best service and price. We definitely plan on using Building Sciences for our future needs as well as recommending them to friends and family. read more

I had Building Sciences out at my home. I had insulation put in the attic, and had a new water heater, central air-conditioner and furnace installed. I have to say from the beginning, when Vanessa visited my house, to Lauren and Abigail in the office and Terrel, the install crew leader, my experience with Building Sciences has been all excellent. They gave me great price, the whole project was done with no money down and a 0% interest loan. The equipment works great and I feel much more comfortable in my house. Since then, my home has been less drafty and my utility bills are down. Thank you Building Sciences. You are the best!!! read more

This company came to the rescue. I just bought my house in August. They helped me figure out what steps to take. I got great pricing for insulation in my walls and to replace my AC and my heating. The old ones were on the last leg! I have a young child at home with bad allergies. They recommended air purification system and installed it as well. Has really helped us. Now I have a navien combi and we love it. The Ac kept us cold all summer. crew cleaned up well and was friendly. The office people were so helpful when I had questions! Two thumbs up to building sciences. read more

My home needed new heating & cooling. Plus the upstairs was always too hot in the summer. Building Sciences was the only company to put together a total solution for me. I was able to qualify for the NJ Clean Energy program. I cant say enough for how the office kept me informed all along the process. Installs were quick and on time. They even cleaned up after themselves every day. I got an Amana system, and while the temperature differences are not 100% solved, they are substantially better. I fully recommend Building Sciences to anyone who needs heating, cooling or insulation. read more
